IMPROVEMENT IN SHlNGLE-MACHINES.

Specification forming part of Letters Patent No. 123,048, dated January 23, 1872.

To all whom it may concern:

Be it known that I, JOHN HENRY RICE, of Oshkosh, in the county of Winnebago and State of Wisconsin, have invented a new and useful Improvement in Shingle-Machines; and I do hereby declare the following to be a full, clear,

and exact description of the same, referencesists in the combination of an oscillating lever and a connectingrod with a rotating double cam and the sliding carriage of the machine,

whereby the irregular jarring movement of the carriage, as ordinarily operated, is effectually overcome.

I do not claim broadly the application of a double cam and lever to a shingle-machine for the purpose of operating the bolt-carriage, as I am aware that this is not new. My invention consists more particularly in the combination of these parts in connection with the connecting-rod, by which the motion is communicated from the cam to the bolt-carriage, as I will now proceed to describe.

The accompanying drawing represents onehalf of a Valentine shin glemachine, called a double-block machine, the otherhalf being the counterpart of that represented. My improvements are shown applied to this machine, though they are, of course, applicable to machines of a difi'erent construction.

L is the saw resting upon a plate or disk at the top of a vertical arbor, I. A is a horizontal driving-shaft, terminating at either end with a pinion, as at C, which drives the bevelwheel B, this being keyed to the shaft F, having its bearings in the brackets O aflixed to the end of the machine. D is a double cam mounted upon the shaft F between the brackets. Motion is imparted to the cam by the driving-shaft 0, through the medium of the beveled wheel B and shaft 1 E is an oscillating lever having a central bolt and nut, M. The lower end of the lever turns freely upon a shaft, H, as a fulcrum, which shaft is aflixed to hangers P, depending from the lower edges of the brackets 0. ()n the bolt, at M, is placed a thimble, which fits with easy contact within the groove of the cam. The upper end of the lever E is connected by a rod, S, with the carriage T, upon which the shingle-bolt K is placed. As the cam is rotated the lever E oseillates upon its shaft, imparting a slow, steady, forward movement to the carriage for cutting the shingles from the bolt and a quick backward movement after the shingles are cut.

Having thus described my invention, what I claim is The upright oscillating lever E and the connecting-rod S, in combination with the double cam D and bolt-carriage T, as herein shown and described, for the purpose specified.
